Added two dao classes

The controller can now inject two classes.
Added EntityFramework Repository models to the project
Using Stream to return and simplified searching for orders

All of the GET services now use IO.Stream so the user can decide what
format to look at.

Collapsed 4 webservices into one so there is a single call to search for
orders.
Fixed the controller and dao to implement simpler webservices

The service layer calls a generic controller method to get a list of
orders, but the dao layer will have separate functions for the different
types.
Cleaned up webservices, mainly on sending images

Fixed the controller to resize images, but that required changing the
webserivce parameters.
Added some mocked data to the Mysql DAO to help with testing.  This will
require two jpegs in C:\Temp, one called logo.jpg and background.jpg
